c2b02608d1 Renamed instance of variables called format to pixelFormat to make a
clearer distinction between pixelFormat and internalTextureFormat.

a36d45e68b Added check to allocateImage() so that if the pixel size wouldn't be computed
unless valid _data already existed on the object.

0f3eaeba46 From Rune Schmidt Jensen - new dds loader. 2003-04-02 18:26:34 +00:00

3975fc9b01 Improved handling of subloading.
Removed the rescalling of images in osg::Image during texture apply, moving
the rescale so it is locally calculated.  This solves an outstanding threading
problem which occured by multiple draw threads all tried to rescale the same
image at one time.

Made osg::Image ptr in osg::Texture2D non mutable as it is no longer modified
during apply.

quad buffers attributes from DisplaySettings values.

78de76f17f Bug fixes to osgText to handle the osgUtil::Optimizer being used on a scene
graph containing text.

Fixed warning in MD2 plugin.

b32c8c65f3 Added osg::Image::AllocationMode enum and associated set/get methods.
osg::Image::setImage has also been modified to require the AllocationMode
mode to be passed to it so that it knows how to delete the data once the
image goes out of scope.

Port the image plugins across to specify the new AllocationMode, and converted
them across to using new/delete in place of malloc/free.

0a5ed26940 Moved the new osg::IndexedGeometry class over the top of the the existing
osg::Geometry class, and removed the temporary IndexedGeometry.  Port the rest
of the OSG across to account for the change in method calls -
osg::Geometry::addPrimitive(..) becomes osg::addPrimitiveSet(..)
2002-10-02 13:12:16 +00:00
Robert Osfield
55215651d7 Renamed osg::Primitive to osg::PrimitiveSet which better reflect what it
encapsulates.

Added new osg::IndexGeometry implemention, *not* complete yet.

Changed the rest of the OSG to handle the renaming og Primitive to PrimitiveSet.

12226e4371 Converted the instances of const built in types being returned from methods
and passed as paramters into straight forward non const built in types,
i.e. const bool foogbar(const int) becomes bool foobar(int).

8353fc0ed6 Removed deprecated code from the distribution.
Added .osg support for Texture1D and Texture3D.

Robert Osfield
83af5e7a95 Added osgtexture3D demo, renamed osgtexture demo to osgtexture2D, and have
added osgtexture1D demo which currently is simply copy of osgtexture2D. I
will be modifying it to do 1D texturing next.

Fixed a bug in osg::Texture3D relating to checking of existance of
texturing.

Merged some fixes to the pfb loader from Ulrich Hertlein.

59a5e800fe Moved #define's for OpenGL1.2 image formats into the include/osg/Image header
to allow compilation of the rgb plugin under Windows with its 1.1 OGL headers.

Added float.h to Math's compile path for VS7 compilation.
2002-08-26 13:04:43 +00:00
Robert Osfield
239068f223 Added new osg::TextureBase, osg::Texture1D, osg::Texture2D, and osg::Texture3D
classes, and changed osg::Texture and osg::TextureCubeMap so that they now derive
from osg::TextureBase.
2002-08-24 19:39:39 +00:00
Robert Osfield
7dfefaf67f Added new osg::Texture::SubloadCallback, and getNumMipmapLevels() to osg::Texture
and osg::Image.  This additions are design to make texture subloading more
flexible.

Robert Osfield
cbeeeefdab Added osg::Drawable::PrimitiveFunctor and TriangleFunctor subclass for
querrying the primitive data inside Drawables.  Moved various support
classes over from being osg::GeoSet based to osg::Geometry based.
2002-06-25 20:27:51 +00:00
Robert Osfield
4f4f68e961 Added support for reading the new OSG_MAX_TEXTURE_SIZE environmental variable
inside the osg::Image::ensureValidSizeForTexturing() method. The
smallest of GL_MAX_TEXTURE_SIZE and OSG_MAX_TEXTURE_SIZE is used for the
final max texture size.

This new env. var. allows users to deliberate cap the size of their textures
so they can test whether their models are limited by texture memory.  If
reducing the max texture size increases performance then you are limited
by texture memory!

dcfef4a023 Integrated submission from Boris Bralo:
Supported added for precompiled mip maps stored in osg::Image, and read
by osg::Texture.

Updates to TerraPage loader for support of compressed texture images and
precompiled mip maps.

7836540bb3 Added osg::Image::setPixelFormat(..) and setInternalTextureFormat(), and
renamed osg::Image::pixelFormat(), internalTextureFormat(),dataType() to
osg::Image::getPixelFormat() etc.  These changes are to bring it more
into line with the style of the rest of the OSG.

Updated the rest of the distribution to take account for these names changes.

c43607c14d Added support for specificing the eye mapping and seperation between the
horizontal and veritical split stereo modes.

Renamed osg::Image::ensureDimensionArePowerOfTwo() to osg::Image::ensureValidSizeForTexturing().

22e8047869 Used a faster method for checking for power of 2 on the image dimensions and
did a check on forcing 16bits textures in osg::Texture (which speeds things
up on the Umea model which is performance bound by texture memory.), the
later check is now commented out.

09d41789da Fixes to osg::Image::createImage(..), and addition of code to Viewer.cpp to support
output of screen snapshot via 'O'.

e85e5a6ce6 Added several new methods to osg::Image to help keep track of memory and added
osg::Image::readPixels to encapsulate glReadPixels.

Reordering of includes in include/osg/Fog and include/osg/Light to remove silly warnings under Visual Studio.

f2ffbdd469 Copied NewCullVisitor over top of CullVisitor and then removed NewCullVisitor.
Added some defines to Image in prep for writing code to determine how big a
pixel is.
2002-04-10 22:10:07 +00:00
Robert Osfield
360247225e Added new osg::DrawPixels class with encapsulates glDrawPixels as and
osg::Drawable.  Added osg::Image::readPixels to osg::Image.

Made osg::LightSource to default to cullActive set to false to that LightSource
nodes don't get culled by default.

84d2d01163 Added support for osg::MemoryManager which is based upon Paul Nettle's
memory manager published at flipcode.com.  This can be turned on
with the OSG_USE_MEMORY_MANGER option which then uses custom global
new and delete operators as well as provide osgNew and osgDelete macro's
which add ability to log line and file from which calls are made.

Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete,
and fixed memory leaks highlighted by the new memory manager.
2002-03-26 23:52:52 +00:00
Robert Osfield
651a22453a Added osg::MemoryManger which is currently based on Paul Nettle's memory manager
published at flipcode.  I havn't adopted Paul's macro's for new/delete etc, but use
osg prefixed versions instead to allow greater flexiblity in handling include
ordering.

Have fixed a couple of new/delete[] problems which existed as a result.

To use the MemoryManager to track memory usage simply add
-DOSG_USE_MEMEORY_TRACKING to the compile line.

Have yet to move the osg from using new to osgNew, will do this next.

c49c62ee15 Integrated various changes worked on at the Glasgow Science Center. Changes
include change the CameraManipulators so they work with double for time
instead of float.  Also added support for DataType to osg::StateAttribute
and StateSet so that they can be set to either STATIC or DYNAMIC, this
allows the optimizer to know whether that an attribute can be optimized
or not.

02ef10fcfa Moved all references to osg::Cloner to osg::CopyOp. 2002-01-29 14:04:06 +00:00
Robert Osfield
f612924a45 Added support for shallow and deep copy of nodes, drawables and state, via a
copy constructor which takes an optional Cloner object, and the old
osg::Object::clone() has changed so that it now requires a Cloner as paramter.
This is passed on to the copy constructor to help control the shallow vs
deep copying.  The old functionality of clone() which was clone of type has
been renamed to cloneType().

Updated all of the OSG to work with these new conventions, implemention all
the required copy constructors etc.  A couple of areas will do shallow
copies by design, a couple of other still need to be updated to do either
shallow or deep.

Neither of the shallow or deep copy operations have been tested yet, only
the old functionality of the OSG has been checked so far, such running the
viewer on various demo datasets.

Also fixed a problem in osg::Optimize::RemoveRendundentNodesVisitor which
was not checking that Group didn't have have any attached StateSet's, Callbacks
or UserData.  These checks have now been added, which fixes a bug which was
revealled by the new osgscribe demo, this related to removal of group acting
as state decorator.

c16fe83d0a Fixed a bug in osg::Image::ensureDimensionsArePowerOfTwo() which only
scaled dimensions if *both* axis wern't a power of two, have fixed it
to rescale if either of the axis arn't a power to two.
